If the overhead is X, and the amount of work that can be done ignoring it is Y, you have Y - X. If you double the amount of work that can be down, but overhead

If the overhead is X, and the amount of work that can be done ignoring it is Y, you have Y - X. If you double the amount of work that can be down, but overhead stays the same you have 2Y - X, which is more than 2(Y - X) = 2Y - 2X. You're over performing doubling by not having to double the synchronization cost.
